Geforce GTX 780 vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which comes with core clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 memory. It features 2304 SPUs along with 144 Texture Address Units and 64 ROPs.

Geforce GTX 780		288384 MB/sec
	Difference: 55680 (19%)

Texel Rate

The Radeon RX 5600 XT is just a bit (about 19%) better at anisotropic filtering than the Geforce GTX 780. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 32304 (19%)

Pixel Rate

The Radeon RX 5600 XT will be much (more or less 112%) faster with regards to full screen anti-aliasing than the Geforce GTX 780, and also capable of handling higher screen resolutions better. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 46576 (112%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
